Abstract
Provided is a secondary battery having a battery case which accommodates an electrode assembly including a cathode, a anode, and a separator disposed between the cathode and the anode, together with an electrolyte, wherein one or more selected from the group consisting of the cathode, the anode, the separator, the electrolyte, and the interior of the battery case include, as a water adsorbent, a first organic-inorganic hybrid nanoporous material which may be regenerated by desorbing 70% or more of a total adsorption amount of adsorbed water at 150° C. or lower; and optionally, a second organic-inorganic hybrid nanoporous material, of which water adsorption capacity is higher than water desorption capacity at a relative humidity p/p0 of 0.3 or less (herein, p0 represents a saturated vapor pressure at an application temperature and p represents a vapor pressure upon adsorption).
